If you look through the Silver Spring Library's shelves to try to find "The Postman," you won't find it; library officials said the book was too fragile to be checked out, but that they'll show it to anyone who's interested.

"We want [books] out in people’s hands," the library director said. "Even if they’re in people’s hands for almost 73 years."

If Gregg wants to read "The Postman" yet another time, she can go to the Toronto Public Library, which has a copy.
